J. O. TABEH, OF SALEM, OHIO, ASSIGNOR TO HIMSELF, O. R. TABER, AND V. S. STETSON, OF SAME PLACE.

IMPROVEMENT IN TRACK-CLEARERS FOR HARVESTERS.

Specification forming part of Letters Patent No. 38,007, dated March 24, ISIS.

To all whom it may concern:

Be it known that I, J. O. TAEER, of Salem, in the county of Columbiana and State of Ohio, have invented a new and Improved Swath- Board or Track-Olearer for Mowing-lvIachines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a plan or top view of my invention; Fig. 2, a vertical section of the same, taken in the line x a", Fig. l; Fig. 3, a side view of the same.

Similar letters of reference indicate corresponding parts in the several iigures.

This invention relates to a new and improved mode of attaching the swath-board to the shoe of the finger-bar, as hereinafterfully shown and described, whereby the swathboard ina-y be attached 'to and det-ached from the shoe with the greatest facility, and when attached to the shoe held firmly in proper position.

The invention further relates to a new and improved mode of attaching` the arm to the swath-board, whereby the former may be readily adjusted higher or lower, according to the height of the grass, and a clean track always obtained, whatever the height of the grass may be.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the finger-bar of amowing-inachine, and B the shoe, which is attached to the outer end of the finger-bar. The back part of the shoe has a slot, a, made vertically in it, and this slot extends entirely through the shoe, and has a curved recess, b, made in each side of it. rIhe form ofthese recesses is shown clearly in Fig. 2. The upper parts of them, it will be seen by referring to the figure aforesaid, are vertical, and they curve outward in semicircular form.

O is the swath-board, which may be of the usual form, and at its inner end or part it is of sucln width that it may fit snugly in the slot c of the shoe B. In the inner part of the swath-boardthere is fitted transversely a pin,

c, which projects at equal distances fromeach side of the swathlboard, and is of such a length that it may fit in the curved recesses b b. The inner end of the swath-board C bears against the inner edge of the slot a, as shown in Fig. 2, and sustains the outer `part of the swath-board, holding it in proper position.

From this description it will be seen that in order to detach the swath-board from the shoe all that is required is to elevate its outer part, and the pin o may be readily lifted out from the recesses b b, the swath-board being held in the same position when the pin is adjusted in the recesses. By this arrangement a very simple and firm attachment of the swath-board to the shoe is obtained,- and one which admits of the ready adjustment of the swath-board to the shoe as well as a ready detachment from it.

D represents an arm, which is of wood, and

fitted within a metal socket, E, which is attached by a screw, ci, to the inner side of the swatheboard. rlhis socket E has a curved plate, c, projecting from its lower edge, said plate having a curved slot, f, made in it, through which a screw, g, passes into the swath-head. The curve of the slotf is a part of a circle of which the screw d is the center, and hence it will be seen by loosening or unscrewing the screw gthe socket E may be raised and lowered from the screw d as a center; and it will also be seen that by screwing up the screw g the socket and arm may be retained at any angle or point within the scope of their movement. Thus the arm D may be adjusted higher or lower, according to the height of the grass being cut, so that the latter, whatever height it may be, will be acted upon or caught by the arm as the machine is drawn along andshoved or forced inward from the outer part of theV machine, so as to leave a clean or clear track for the team at the succeeding bout, or during the cutting of the succeeding swath.

I would remark that the socket E is so formed as to cause the arm D to have the usual angle with the swath-board, as shown in Fig. l. Y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The method of attaching the swath-board C to the shoe B of the finger-bar as herein shown and described-to wit, by means of the pin c, secured transversely in the swath-board,

and the recesses b b infth'e sides of the slot@ -being attached to `@he swath-board byrascrew,
